Title: Disc brakes
IPC: F16D55/2255
Filed: 1978-06-19
Abstract: A disc brake suitable for a bicycle or light motorcycle comprises a carrier member 2 which is secured to the frame of the bicycle or motorcycle and which slidably supports a pair of brake pads 10, 11. Two caliper members 15, 16 each have arms 18, 19 which terminate in contact areas 22, 23 in engagement with the pads 10, 11.

Title: X-ray system signal derivation circuits for heat unit indicators and/or calibration meters
IPC: H05G1/26
Filed: 1978-09-15
Abstract: Milliampere and kilovolt signals are monitored from the X-ray tube system high tension transformer. These signals may be connected to a heat unit indicator or a calibration meter or both. With the heat unit indicator, the heat level in an X-ray tube anode is monitored and referred to the level corresponding to the ambient room temperature as zero reference. As successive single exposures or series of exposures are made, the X-ray tube heat loading is automatically monitored and displayed. The cooling characteristics of the tube are automatically reflected in the reading. A calibration meter may be connected to the signal derivation circuitry to indicate a plurality of operating parameters. The circuitry includes automatic scaling device for maintaining the relatively accurate signals required for the accurate operation of the heat unit indicator and the calibration meter.

Title: A steering device for a vehicle comprising hydraulic power-assisted steering facilities
IPC: B62D5/065
Filed: 1980-04-17
Abstract: A steering column 11 of a vehicle is connected to a meter 12 which measures the torque produced in said column when a steering correction is made.

Title: Circuit arrangement for an electric drive-in apparatus
IPC: B25C1/06
Filed: 1980-07-21
Abstract: A magnet coil (10) is connected to a power source by a power switch (11) controlled by a control stage (14). The control stage (14) has a key (13) connecting it to the a.c. voltage and is itself responsive to an auxiliary control stage (16) including a zero-crossing detector (17) which transmits an auxiliary control pulse in phase with the a.c. voltage to the control stage (14) at or near the zero crossing of the a.c. voltage. The control stage (14) can delay the operation of the power switch (11) relative to the auxiliary control pulse by means of a time delay stage (15), thus providing an output of a fraction of a single half wave. Hence the power of a single impulse of the magnet coil can be reduced. Applied to a nailing or stapling machine, this allows reduced force to be used with delicate materials. <IMAGE>

Patent GB-2098736-A (GB)
Title: Change-gear indicator
IPC: B60W50/14
Filed: 1981-04-22
Abstract: An indicator panel 20 has an array of LED's 25A to 25Q to provide an indication to the driver of a road vehicle, particularly a diesel-powered truck, when he should change to the next highest gear during acceleration from rest or low speed. The LED's are lit progressively as the engine speed increases in each gear and, when lit, emit green light if the engine speed is below the optimum change-up speed for that gear. When the engine speed begins to exceed the optimum change-up speed, the next LED illuminated produces red light to the driver. An audible warning may also be produced. If the driver does not change up in response to such warning, further red LED's will show and a more strident audible warning may be given. The change-up speeds to which the system responds are pre-set so as to be the optimum speeds for increased fuel efficiency. The change-up speed corresponding to the lowest gear is relatively low and increases successively for the successively high gears. The system may be associated with engine speed control or limiting means so as positively to prevent further increase in engine speed if the driver ignores the warning. The system may also produce an indication of the optimum engine speeds at which the driver should change down to the next lower gear during vehicle deceleration.
